To allxwwm t may concern:

Beit known that we, WILLIAM H. GARLAND and HERMANN ScHULzE Bissen, bothof Rochester, in the county of Beaver and State of Pennsylvania, haveinvented a new and useful Improvement in Sewing-Machines; and we dohereby declare the following to be afull, clear, and exact descriptionthereof, reference being had to the accompanying drawings, in

Like letters of lreference indicate like parts 4o in each.

The machine shown in the drawings is of the well-known Singer type,7 andthe improvement consists in providing it with oertain mechanism wherebythe needle is caused 4.5 to change its position laterally with relationto the line ot' motion ofthe sewed cloth.

lt also consists in providing the shuttle with suitable mechanism forcausing it to move in unison with the needle, and in several other newand improved devices,which will be here inafter described, and moreparticularly indicated in the claims.

Heretofore a difficulty in the operation of sewing-machines whichproduce a serrated or zigzag stitch by the lateral oscillation-of theneedle-foot is that the zigzag appears only on the upper part of thecloth, and not under neath, and that the reciprocating shuttle oftenmisses the loop of the thread and dropsits stitch, by reason ofvariation in time of the arrival of the shuttle-point at theloops formedin the two different lines.

A principal object of our invention is to obviate these difficulties.

The motive power of the machine is derived from a belt-wheel a', whichis driven bythe usual treadle arrangement, and is am ed to a rotaryshaft, a. The rotation of the shaft a gives to the needlefbar b itsnecessary vertical reciprocating motion by means ofthe usual cam,b, androller b2. The oscillatory movement of the shuttle r is imparted fromthe shaft a through beveled gear-wheels a.'l and c, the gear-wheel cebeing ot' onehalf the diameter ot' that of the pinion c, so that theshaft o', to which the latter is atlixed, performs one revolution whilethe shaft d revolves twice. The shuttle-lever d, which is geareddirectly to the shaft c, as hereinafter described, makes one completeoscillation for each revolution of the shaft, and the shuttle willtherefore have moved once forward or backward while the needle-bar hasmade a complete double motion and has driven its needle c through thecloth once. The lower end of the needle-bar l) is provided with avertical slot having lateral grooves within which moves a needle foot orslide, f, as shown in Figs. 1 and 7 of the drawings. The needle-foot haslateral ribs f3, which fit movably in these grooves. It also has aspringplate, f, which ts against the needle-bar at the base of thevertical` slot and prevents accidental displacement of the foot. Theneedle e is secured to the needle-foot by a set-screw e.

rlhe needle-foot f tapers to a point, f2, atits top, and is movablelaterallyby the following mechanism: The xed arm g of the sewingma chinehas a recess at its base through which the vertical needle-barb passes.Within this recess, and movable laterally with relation to the course ofthe cloth, is a slide-frame, h, having two parallel and oppositerollers, h. The rollers are separated, so that the needle-bar b may passfreely between them, and so that the Widest part of t-he needle-footf,which projects from the needle-bar laterally, may equal in width thedist-ance between the rollers. Sufficient space is left in the recess toallow a considerable movement of the slide from side to side. When theslide is xed and the needle-bar lowered, as shown in Fig. 12, so as tobe off the center of the space between the rollers, the rise of theneedle-bar will cause one of the tapered sides of the needlefoot tostrike against one of the rollers of the slide-frame, and to move theneedle-foot laterally in its grooves in the needle-bar until the otherside of the foot strikes the other roller. By moving the slide-framealternately backward and forward after each descent of the needle-barthe needle-foot will be given a corresponding reciprocating` movement.It is in this manner that we produce the desired zigzag stitch. If theslide-frame is kept stationary, the needle-foot will not move back andforth, and a straight stitch is made. The slide-frame h is moved in thismanner by means of the intermittentgearwheelsi Z. (Shownin Figs. 1 and7.) Thegear-wheelissituatewithinthearing, and rigidly mounted upon thedrive-shaft a of the machine. It is provided with a series of gear-teethextending about one-half of its circumference. The rest of thecircumference t is untoothed and convex, the diameter of this part beingpreferably bounded by the pitchline ofthe two gear-wheels. The othergearwheel, t, is rigidly mounted on a shaft, j, and is provided with twoopposite series of gearteeth, each having the same number of cogs as ison the single series of the gear-wheel Z, and capable of meshing intothat series. The series of teeth on the wheel j are separated by twoopposite lock -teeth, Z, the peripheries of which are concave, theconcavity being determined by the convexity of the untoothed part of thegear-wheel Z, so that when these two parts are in conjunction, as shownin Fig. 7, the gear-wheel Z may revolve freely and in contact with theconcave lockingtooth. Suppose the gear-wheel to be revolvingcontinuously and the two gear-wheels Z and Z to be in the relativepositions shown in Fig.- 7, with one of the concave lock-teeth Z2 incontact with the convex part is of the wheel Z. It is evident that thelock-tooth will hold the gear-wheel t" and its shaft'j stationary untilthe first tooth of the toothed segment of the gear-wheel t' engages theside of the lockingtooth, thereby releasing the part i3 therefrom. Thewheel Zwill then begin to revolve with the cog-wheel t', and willcontinue to do so until the opposite lock-toothJ, has reached the convexpart of its periphery, when the driven wheel will again come'to rest andwill remain so for another semi-revolution of the drive gear-wheel ZZ.e., un'til the toothed segment of the latter wheel again engages theside of the lock-tooth. In this manner there will be a continualintermission of motion of the driven wheel Z. It will rotate for asemi-revolution during one semi-revolution of the gearwheel ,-and willbe at rest during the other semi-revolution, and will altogether performone-half as many revolutions as the drivewheel.

We do not desire to claim the combination of the two lock-gear wheels Zt, of the peculiar construction described, because it has been made thesubject-matter of a separate application for Letters Patent, filedDecember 20, 1884, Serial No. 150,801. The shaftj has its bearings inthe sewing-machine arm g, and just back of the lock-gear wheel Z it isprovided with a disk, k, having a rectangular slot, k', which extendsacross the center of the disk. At the point where the disk fits upon theshaft 7' the latter is square, so as to fit within the slot k. When therotatory shaft is at one end of the slot and in the center ofthe diskthe latter will rotate concentrically; but when the disk is moved untilthe shaft is at the other end of the slot the disk will become aneccentric. The greater the distance of the axis of the shaft from thecenter of the disk the greater will be the throw of the ca'm. In orderto make the eccentric thus mechanically adjustable, there is a sleeve,Z, which fits upon the squared part of the shaft back of the disk k, theinternal bore of the sleeve being also squared, so that it must rotatewith the shaft, and may be movable thereon toward and away from the faceof the disk. The shaft]` terminates in the sleeve Z, and the latter hasits hearings in a suitable box, Z, attached to the horizontal arm s' ofthe machine. Swivelcd within the rear end of the sleeve Z is ahorizontal shaft, m, a part of which, m, is screwthreaded and bearsWithin a female screwsocket, g2. 1f now the shaft m be turned, the screwm g2 will cause it to push the sleeve Z on the shaftj toward and awayfrom the disk la, according to the direction of rotation of the shaft.One of the arms of a toggle-joint lever, a, is pivoted to the squarepart of the shaft j, while the other armis pivoted eccentrically to thedisk k. An arm, n', is pivotally connected with the knee-joint of thetoggle-lever at one end, and at the other end is pivoted to the sleeveZ. When, therefore, the sleeve is moved toward the disk k by the turningof the horizontal vshaft m, it will spread the legs of the toggle-jointn and will move the disk upon the shaft j, so as to make it aneccentric,as before described. When the shaft m is re versed, it will draw backthe sleeve Z, thus bringing the legs of the toggle-joint together anddrawing the center ofthe disk toward the axis of the shaft.

In order to secure steadiness of action, we prefer to have two sets oftoggle-joint levers acting on the disk k, one on each side of the lOOIIO

IZO

shaft and both arranged and operated in thel manner above described.(See Fig. 15.)

The adjustable disk lc is provided with a circumferential yoke orannulus, o, which is mounted loosely on its periphery, so that the diskmay turn readily therein. The annulus 0 has a rigid arnnp, which extendsdownward vertically, and is pivoted at its extremity to an auxiliaryarm, q', which is pivotally and eccentrically connected with a rotatorydisk or rolier, q. The roller q is connected with the slide-carriage h,an arm of the latter being eccentrically pivoted to the roller. If nowthe sleeve Z be adjusted so as to make/the disk la an eccentric, it isclear that the intermittent revolution of the latter will act on theyoke o in such manner as to cause the rod p to rise and fall with eachrevolution of the disk, there by partially rotating the roller qbackward and forward,and through it giving a horizontallyreciprocatingmotion to the slide'frame 7L. At each forward or backward movement ofthe slide-frame h the needle-footy, st-riking 'against its rollers, willmove correspondingly from side to side of the needle-bar b. j j

The slide-carriage h is actuated primarily by the intermittent rotationof the lock-gear wheel t'. This wheel and the disk k revolve onehalfwhile the shaft a revolves once, and while the needlebar b performs onecomplete reciprocation. This semi-revolution of the disk k is sufficientto throw the slide-frame It forward or backward, as the case may be, forits full length, and its action is so timed as to be during the downwardstroke of the needle'bar. The slide will then be locked stationarilyuntil the needle-bar, having risen, has engaged the needle-foot with therollers ofthe slide and has shifted its position. Then as the needlemoves down in a different vertical line the eccentric disk lc will againmove the roller, so that the upward stroke of the needle will` replacethe needle-foot in its original position, as before described. In thismanner there is kept up a continual backward and forward movement ot theslide-frame lz., and a corresponding vibration of the needle, onemovement occurring before each entrance of the needle-point into thecloth. The position of the puncture of the needle being thus regularlyshifted a zigzag stitch is produced. It is evident that the extent ofmotion of the slide-carriage h, and the consequent width ot' the zigzag,is determined by the throw of the eccentric It, and that this throw isaccurately regulable by the screwing or unscrewing of the shaft m. Vhenthe disk 7c and shai'tj are made concentric, there will be no motion ofthe needle-point, and consequentlyno zigzag stitch.

Instead of the roller g a bell-crank lever or other mechanicalequivalent may be employed to transmit the motion ot' thc eccentric ltto the slide-frame. rlherollers of theslide frame h need not be rotary.It' not made so, they will be less advantageous than if made as hereinshown and described, but would be equivalents of this feature ot' ourinvention, and we desire to cover such construction in the followingclaims.

Ve will now describe the means whereby the shuttle is caused to changeits course correspondingly to the change of position of the needle-footf. Figs. 4, 5, and 6 show the arrangement of the parts underneath thebedplate P of the machine, the cloth-feeding arrangement being omittedfor the sake of elearness, because it is of the usual construction andwell understood. The vertical pinionshaft c, which gears with and isdriven by rotation of the shaft a, is provided near its lower end withan adjustable eccentric disk, s, simi lar in all respects to the disk 7con the shaftj, before described, havinga togglelevcr, s', and beingmounted upon a square neck of the shaft, so as to be movablehorizontally thereon in its slot s2. rlhe disk s is surrounded by aloose yokeannulus, s, like the annulus o, and having a Similar rigidarm, Si. In Fig. 4 the disk s is shown concentric upon the axis c', andin Fig. 5 it is eccentric thereon.

Below the disk s on the shaft c is the cam P', for operating thecloth-feeding mechanism, and below it is afiixed the eccentric disk t,which operates the shuttlelever d. The shut` tile-lever d is pivoted tothe under side of the bed-plate P at d", and is caused to oscillate bythe eccentric t through the medium of the mechanism shown in Fig. 6 ofthe drawings. A pitman, di, at one end is connected eccentrically to thedisk t by a crank'pin, t', and at the other to a lever, dt. Thelatterlever connects pivotally at one end with the bed-plate of the machine,an-d at its other end with a link, d', which forms the connecting-linkbetween the lever d2 and the rear end of t-he shuttle-lever d. rlhe pind, upon which the lever d is pivoted, is mounted uponaslide, w, whichmoves in a suitable groove under the bedplate P. This slide is pivotallyconnected with the arm s of the eccentric ring s3. lf, therefore, theadjustable disk s be made eccentric on its shaft c', it is evident thatits rotation will act on the annulus s3 so as to impart to the slide fwand to the lever d a longitudinally-reciprocating movement.

Rigidly attached to the slide w,and movable backward and forward withit, is a shuttlerace frame, a, which is heldin position against theunder side ofthe bedplate P by means of a set-screw, u, which passesthrough a slot, n3, in the frame into the bed-plate. At the end of thistrame a is the usual circular shut tile-race, a', which serves as aguide to the shuttle r as it moves backward and forward through the loopofthe thread from the needle c. rlhe consequence is that when the disk sis made eccentric the shuttle-race a will move backward and forward withthe slide w and with the shuttle-lever d, so as to be always in contactwith the shuttle to act asa guidetherefor. The action of the eccentricdisk s is so timed with relation to the eccentric k that when the latteris at its highest or lowest po- IOO IOS

IIO

sition, and the sliding fra-me h moved either backward or forward to'itsfullest extent, the throw of the eccentric s may also be at its highestor lowest point corresponding to the position of the cam 7c. The shaftc', which drives the eccentric s, revolves only one half as fast as doesthe main shaft a, thusgiving the camsthe same number of revolutions fora given time as has the intermittent cam 7a, which actuates theneedle-foot. It will therefore be apparent that the movement of theshuttle r and the shuttle-race will exactly correspond with the lateralmovement of the needle e. The action of the eccentric s is also sotimedwith relation to the eccentric t, which oscillates theshuttle-lever, that the former may have-moved the lever and the shuttlerace completely forward or backward when the shuttle passes the pointwhere the needle enters the cloth.

rThe shuttle r is shown in Figs. 6, 13, and 14. It is provided with theusual bobbin, R, from which the shuttle-thread is unwound, but it isunlike the ordinary shuttle, in that it is so pointed at each end as tobe capable of traversing the loop and of sewing during its forward andbackward motion. This is made possible by the gearing of the shaft cwith the main shaft ,which, as before stated, gives the shuttle-leveronly a single movement for each time that the needle enters the cloth.The movement of the shuttle is therefore slow and easy, and by means ofthis part of our improvement we are enabled to overcome the difficulty1in operation which has heretofore proved so objectionable tosewing-machines using a reciprocating shuttle.

They bobbin R is provided with a brake for regulating the tension ofthethread which is drawn from it. It consists of a spring, R2,

'which extends over a recess in the upper part ofthe shuttle, whenceitis bent downward, so as to press against a fixed washer, R', on thebobbin shaft R. A set screw, B3, passes through the spring into thebottom of the recess, and itis evident that as the former is screweddown it will cause the spring to bear correspondingly upon the face ofthe washer, so as to eXert an adjustable friction and resistance to therotation of the shaft B.

The arrangement of the shuttle-carrier R4 also forms a part of ourinvention. It is mounted upon a neck at the end of the shuttle-lever d,and is provided with a spring, R5, which bears against a shoulder, RG. Asmall plate or stop. BF, is arranged on the end of the lever d and seatsagainst the face of the carrier B4. rIhe spring B5 keeps theshuttlecarrier against the plate and at a proper distance from theshuttle-race a, to keep the shuttle r in position between them. Toremove the shuttle the carrier BJ* is pushed away from the shuttle-raceand against the spring R5, thereby releasing the shuttle and renderingthe substitution of a fresh one easy.

The latter is the purpose of our invention, and its fulfillment doesaway with a difficulty which has yheretofore caused considerableannoyance.

The mechanism for adjusting the eccentric disk s is yet to be described.It consists of a vertical shaft, E', which has suitable bearings in thearm g ofthe machine, and is provided at its base with a gear-wheel, A,which meshes into a'gear-wheel, B, of equal diamet ter and number ofteeth. The gear-Wheel B fits loosely around the vertical shaft c', andis provided with a screw-shank which works in a female screw within thebearings B of the shaft o. It is also provided at its base with acoupling-sleeve, B2, which is rigid to the gear-wheel B and looselycouples it with a collar', G, which is mounted upon an angular shank ofthe shaft c', so that it will rotate therewith and still be movableupward and downward thereon. The lever which connects with the knee ofthe toggle-lever s of the disk s is also pivoted to the collar G, sothat as the collar is depressed it `may spread the legs of the toggleand adjust the disk eccentrically upon the shaft c', as before eX-plained with reference to the toggle n of the disk k. The upright shaftE is provided with a worm-wheel. E2, into which meshes a pinionscrew, D.By turning the pinion the shaft F/ will 'be caused to turn and torotate' the pinion B. The threaded shaft of the latter pinion acting onits bearings in B will force disk s to become eccentric upon its axis.'

Turning the pinion D in a reverse direction brings the toggle-legstogether and makes the disk s concentric again. The periphery of thegear-wheel Ais made somewhat broad, so that the wheel B may not bethrown out of gear as it moves downward on its shaft.

The upper end of the same shaft E which operates the toggle-lever s isprovided with a beveled pinion, E, which meshes into a beveledgear-Wheel, F, on the horizontal shaft m. Thel latter gear-wheel isloosely mounted upon its shaft m by a spline or feather, (shown in Fig.1,) which causes revolution of the shaft E to turn the shaft m, whilepermitting the latter to move lengthwise without throwing the gearings Fand E out of gear.

Asbefore stated, the shaft m is screw-threaded at m', so that when it isrotatcdit will move lengthwise and act upon the toggle-levers n,throwing the disk k into an eccentric or concentric position. It willtherefore be apparent that the same motion of the pinion D which makesan eccentric of the disk k will also 4move the collar G downward,spreading the togglelinks\s and making the disk s an eccentric. Thepitch of the thread m on the shaft m is so made that a given rotation ofthe pinion D will move the shaft m and the collar G the same distance,so as to make the eccentricity of both disks r: and s equal. By means ofthe pinion D the width of the zigzag stitch can be varied instantly andwithout slackingthe running of the machine, and by reversing the pinionto its fullest extent both disks can be made concentric and the machinecaused to sew a straight stitch. It will be observed that during theside motions of the needle 5e, required for the zigzag stitch, theshuttle r moves correspondingly and through the same distance, so thatit cannot miss the loop of the needle, and will produce a zigzag stitchon both sides of the cloth.

This machine is also capable of sewing button-holes, overseaming, anddarning, and it is evident that if the needle-foot is provided with twoneedles standing a given distance apart and in a line lateral to thefeed of the cloth, so that the loops of the two threads vare formedopposite each other on the outer side of the needles lateral to the feedof the cloth, and that if the shuttlelever d be branched off andprolongated fromits shoulder R, passing be low the shuttle and the race,so as to carry a second shnttleof a cresent shape opposite the firstshuttle and distanced from it the same distance as the two needles areset apart by the shuttlerace, the machines operating under suchconditions will sew two separate straight lines, and eventually, ifsewing zigzag stitch, a double zigzag stitch on both sides of the clothwill result, because two needles with their two respective shuttles willparticipate in the motions.

VVe are aware that a vibrating needle-bar and a shuttle having devicesfor regulating or stop-` ping tlie vibratory movement is described inEnglish Letters Patent No. 2,649 of 1865, and we do not desire to claimthe same, broadly.

That we claim as our invention, and desire to secure by Letters Patent,is-
